Hi Hinko,

The waveform record doesn't actually support ENUM, it just doesn't bother to define its own recordtype-specific list of data types, but instead uses a generic list from base.  I think your best move is to use char or uchar and adopt the standard zero-is-false-nonzero-is-true.

Subject: waveform ENUM FTVL or BOOL FTVL

Hi,

Our Linux OS based instrument will be running soft IOC. The instrument 
supports various data types. One of the data types that I have trouble 
supporting in EPICS is array of bool values. My intention was to use 
ENUM FTVL for waveform but the problem I'm seeing in the IOC shell is:

missing record support entry table Record Support Routine (get_enum_str) 
Record Type waveform PV h:b::adllr4:adc_module:dc_rej_bypass-I.VAL  dbGet


I just wanted to confirm that for waveform record FTVL ENUM is indeed 
supported. What am I doing wrong?

Here is the PV definition:
record(waveform, "$(H)$(B):adllr4:adc_module:dc_rej_bypass-I")
{
         field(DESC, "TBD")
         field(INP, "boards.adllr4.adc_module.dc_rej_bypass")
         field(DTYP, "liberaGet")
         field(NELM, "9")
         field(FTVL, "ENUM")
}

Note that using other FTVL values works, but they are not "restrictive" 
enough to allow only '0'/'1' or 'false'/'true' values.


Best regards,
Hinko
